A hundred and one years ago today, the first controlled, powered, heavier-than-air flight took place. There was a much bigger deal about it last year, centennials being much more newsworthy than hundred and first anniversaries, and it was spiced up by the first supersonic flight of SpaceShipOne on the same day. In fact, looking back now, that’s probably the event that started off a very remarkable year in space–2004, even though it was a couple weeks early. I’ll put together a year-end review of what happened in space this year. In very many ways, it was the most exciting year, and one more filled with hopeful portent, since the 1960s.
